    Press buttons until warm air comes out of the vents. The display is probably dead.

    I have a 93 Suburban with the digital display, and it went out also.
    you have to do a little work, to find this connector, but I bet this is your problem.
    Do you know the center vent section where your equalizer, cd player or tape deck would go? Remove that.
    Also, remove the heater control. In between these two openings, is a 6 pin connector with 4 wires. From my pictures they look black, brown, tan and white. It is actually behind the plastic between these two openings. If this is the problem, pull both sides through a hole behind the heater controls to splice the bad ends.
    I attached a couple of pictures. In one, I circled the plug, and also where to pull them through to fix. Not enough wire to do it anywhere else. The other picture shows the burned connector. Good Luck.

    Oh sorry... I thought I replied. I did get it fixed and it was the control module itself. I bought a used one for 30 bucks from the junk yard and I got amazing heat now! Thanks for the help. Sorry it took me so long to reply

    Good deal.
    When mine broke, I bought a used one I think for $60. Then when I went to put it in, it was working. Then when it stopped again is when I found the bad wire. Glad to hear you got it fixed.
